      Blank page after login from all browsers from every computer.

      It's freshly installed Jenkins. Just after Setup Wizard with Install suggested plugins. Then in wizard dialogue user was created. And after that all attemts to login with this user lead to nothing.

       


      For those who just need to fix it right now:

      You can restart Jenkins with this URL: 

      http://<jenkins.server>/restart

       or you can restart host, where Jenkins installed, or restart Jenkins in another way, depending of your installation.

          I saw this bug previously and know that

          http://<jenkins.server>/restart

          will help. And I wont be able to reproduce bug after restart (I tried before).

          Luckily, I have VM snapshot. So, this state most likely can be reproduced as many times as needed.

          The question now is - how i can gather more information without restarting Jenkins?

          As I found, I can fully access Jenkins and it works fine when I use URL other then mainpage. And mainpage is still blank. So I can use loggers with http://<jenkins.server>/log/. Trying to figure out which loggers can help me.

          in Tread dump we see jenkins.install.SetupWizard$1.doFilter(SetupWizard.java:627) so, SetupWizard is still in a filter chain
